The Islamic State in Syria and Iraq: A 
Possible Threat to Jordan?

As Congress debates whether to authorize and fund the continued use of 
U.S. force in Iraq against the Islamic State (IS, previously referred to as 
ISIS or ISIL), lawmakers may consider if the Islamic State poses a threat 
not just to Iraq but to neighboring countries such as Jordan, an important 
U.S. partner. Recent territorial gains by the Islamic State in Iraq and Syria, 
combined with its ambition to reestablish a global "caliphate," have led to 
speculation that the terrorist group could possibly target Jordan. Jordan may 
be an attractive IS target: many Islamist extremists consider King Abdullah 
II an apostate ruler, and the kingdom has strong ties to the West and 
maintains relations with Israel under a 1994 peace treaty. (For more on IS 
in Iraq, also see CRS Report R43612, Iraq Crisis and U.S. Policy, by Kenneth 
Katzman et al.) 
Nearly a decade ago, during the height of the U.S. military presence in Iraq, 
the Islamic State's predecessor (Al Qaeda in Iraq or AQI) repeatedly plotted 
against Jordan. On November 9, 2005, Iraq-based terrorists carried out 
suicide bombings at three Western-owned hotels in Amman, killing 58 
people.Jordanian intel igence reportedly provided information that U.S. 
forces in Iraq used to track and kill the head of AQI, Abu Musab al Zarqawi 
(a Jordanian), in June 2006. 
Jordanian and U.S. authorities are concerned not only with IS infiltration into 
the kingdom, but also IS radicalization of Jordanians who have fought in 
Syria. Although Jordan has experienced far less social unrest and 
homegrown Islamist radicalism than some other Arab countries, the 
kingdom is home to several areas where manifestations of anti-government 
sentiment are high, economic prospects are poor, and sympathy for political 
Islam appears to be prevalent. Many Jordanians also have tribal or kinship 
ties with Sunni communities in Iraq and Syria, whose sense of persecution 
has driven support for the Islamic State and other extremist groups. In 
Zarqa, an industrial city near Amman that has long been a source of Islamist 
militancy, dozens of young Sunni residents have traveled to Syria, 
reportedly comprising one third of all Jordanian foreign fighters participating 

in the Syrian civil war. In the southern town of Ma'an, an area prone to 
periodic anti-government unrest, a small group of residents unfurled pro-
Islamic State banners during a May 2014 protest, and IS propaganda 
distributed via social media has cal ed on Ma'an residents to "wage jihad" 
against Jordan's "apostate criminal regime."

domestic support for the Islamic State. 
From a religious angle, the 
government recently released from prison several preachers who have long 
been associated with promoting Al Qaeda-like ideology after they publicly 
condemned the Islamic State. The most prominent of these clerics is Abu-
Muhammad [Mohammed] al Maqdisi, who has declared the Islamic State to 
be a deviant organization and calling on his followers to join the rival Al 
Nusra Front in Syria, a U.S. designated Foreign Terrorist Organization (FTO) 
allied with Al Qaeda's core leadership. 
Politically, Jordan has long cultivated ties to Sunni tribes in western Iraq who 
have either joined the Islamic State or refrained from stopping its advance. 
Jordan has repeatedly criticized the political marginalization of Iraq's Sunni 
Arab population, and Jordanian intelligence has reportedly permitted Iraqi 
anti-government groups to operate inside the kingdom. Some of Jordan's 
actions have strained its ties with its neighbor, notably after the kingdom 
hosted the "Amman conference to save Iraq," in which 200 Sunni Iraqi tribal 
and other leaders convened in Jordan and called on the international 
community to end its support for the former Maliki government. 
Additionally, Jordan has increased its border security and efforts to track 
foreign fighters. In late June, Royal Jordanian Airlines began requiring that 
al  Jordanian male passengers between the ages of 18 to 38 prove that they 
have registered with the military before they are permitted to board an 
airplane. King Abdullah II also traveled to Russia's Chechen Republic in June, 
possibly to coordinate efforts to prevent Chechen fighters embedded with IS 
militants from infiltrating the kingdom's Chechen minority community. 
Moreover, local authorities have reportedly arrested IS sympathizers and 
other individuals who have returned from suspected fighting Syria. According 
to Steve Simon, a former senior official at the National Security Council, if 
security forces are relatively measured in their actions, "they'll minimize the 
possibility of an ISIS insurgency by keeping fence-sitters where they are and 
not inadvertently convincing them that no matter how peacefully they 
protest, the police will come after them." King Abdullah II is also currently 
reviewing amendments passed by parliament to a 2006 anti-terrorism law 
that would criminalize the use of the Internet to "facilitate terrorist acts or 
back groups that promote, support or fund terrorism." Some watchdog 
groups have warned that the draft law could be used as a tool to quash 
domestic dissent under the guise of countering terrorism. 
To date, no major confrontations between the Islamic State and Jordan have 
been reported, as observers believe that the Islamic State may try to 
consolidate and expand its presence in Iraq and Syria before confronting the 
Jordanian armed forces, which enjoy strong Western military backing. In the 
meantime,commerce between Iraq and Jordan has slowed, and officials 
remain concerned over the risk of sporadic terrorist attacks against "soft 
targets" inside Jordan. But, according to one analyst, "if ISIS is not rolled 
back in Iraq, terrorism perpetrated by the radical Islamist group will 
eventually reach the kingdom." 
U.S. Policy Implications 
On August 25, Chairman of the Joint Chiefs of Staff General Martin Dempsey 
said that any long term strategy to defeating the Islamic State would require 
the assistance of regional partners such as Jordan. President Obama 
reportedly is seeking to build a multilateral coalition (to include Australia, 
Britain, Jordan, Qatar, Saudi Arabia, Turkey and the United Arab Emirates) 
to join the United States in countering the Islamic State. Several media 
reports suggest that Jordanian Special Operations forces assisted U.S. troops 
in an unsuccessful attempt to rescue American journalist James Foley, who 
had been held captive by the Islamic State prior to his recent execution. 
Congress has supported efforts to bolster Jordan's security as part of an 
already a robust bilateral military partnership. The House and Senate 
versions of the FY2015 State and Foreign Operations Appropriations bills 
(H.R. 5013 and S. 2499, respectively) would appropriate $1 billion in total 
economic and military aid for Jordan. S. 2499 states that a portion of these 
funds may be used for Jordan's security requirements along the border with 
Iraq and Syria. Congress also is considering the FY2015 Defense 
Appropriations Act (H.R. 4870). The version of H.R. 4870 reported out of the 
Senate Appropriations Committee includes Operations and Maintenance 
(O&M) appropriations that may be used to "reimburse the government of 
Jordan, in such amounts as the Secretary of Defense may determine, to 
maintain the ability of the Jordanian armed forces to maintain security along 
the border between Jordan and Syria."
